make HTTP request with custom headers

[Andrey Torba]

Hello,

I need HTTP request with custom headers:

(let ((url-http-extra-headers '(("name" . "value"))))

  (url-http (url-generic-parse-url "http://myhost/";)
            (lambda () (print "hello"))
            nil))

I use `url-http-extra-headers' variable from url-http.el module to
pass extra headers but no effect.
What do i do wrong?
